Why is the brake light on the dashboard always on?
2 Answers
The brake light on the dashboard staying illuminated is generally caused by a low brake fluid level in the reservoir, indicating that the vehicle is lacking brake fluid, which should be replenished promptly. Typically, there is a sensor inside the brake fluid reservoir. When the brake fluid level drops, the warning light will illuminate to alert the driver of a potential brake system issue. If there is no brake fluid leakage or the fluid level has only slightly decreased, it suggests that the braking performance remains good, but regular checks of the brake fluid level are still necessary. A drop in brake fluid level should be addressed by timely replenishment. If the brake fluid is being consumed rapidly, it is advisable to inspect components such as the brake lines, brake calipers, and brake hoses for potential leaks, which should be repaired immediately if found. Additionally, if pressing the brake pedal results in an excessively long braking distance or occasional brake failure, the vehicle should not be driven further under such conditions.
As an experienced driver who has been behind the wheel for many years, I've found that the brake light staying illuminated on the dashboard is a common issue, but it should never be taken lightly. The most frequent cause is insufficient brake fluid—you'll need to pop the hood and check the level in the brake fluid reservoir; if it's below the minimum mark, top it up promptly. Another possibility could be a faulty sensor or switch, and sometimes poor electrical connections can also trigger false warnings. My advice is to first do a quick check of the fluid level yourself. If the problem persists, head to a repair shop immediately, as brake system failure poses extreme risks and could lead to accidents. Don't delay—safety comes first. Additionally, regular brake maintenance helps prevent issues; I now get my brake components inspected annually.
